CORE-WIBE-BENDING MACHINE.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed May 10, 1918. Serial No. 233,664.

To all lwho-1n it may concern Be it known that I, Josnrn A. LAcoURsn, -a citizen of the United States of America, residing at Muskegon Heights, in the count-y of Muskegon and State of Michigan, have invented certain new and useful Improvements in Core-iVire-Bending Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

,The present invention relates to a wire bending machine and one which is particularly adapted for bending lengths of wire into various shapes for use in reinforcing and strengthening'sand cores used in the operation of molding. Many different shapes and varieties of wlre forms are needed to strengthen and reinforce different4 shapes and forms of sand cores, and it is an object and purpose of my inventionto provide a. machine with several adjustable part-s which may be fixed in different positions with respect to each other and the remainder of the machine, whereby a great variety of wire forms may be readily made with a single machine. Another object and purpose of the invention is to make a machine in whicha plurality of wires may be bent at one-and the same time into a desired shape on the machine. Still further objects and purposes of the invention are the production of a machine of this character of a relatively simple construction, one which may be very readily operated when once set for a certain form to bend a large number of wires in a short time, and one which may be adjusted to bend other forms of wires in a very easy and simple manner. All of these features, together with many others not specifically enumerated at this point, will appear as understanding of the invention is had from the accompanying drawing, in which,

Figure 1 is a front elevation, partly in section, of thewire bending machine.

Figs. Q and 3 are elevations, respectively, of opposite ends of the machine.

Figs. 4 and 5 are plan and front elevations, respectively, Of an element of the machine which will appear more fully hereafter, and

Figs. 6 to 11 inclusive yrepresent a few of the many different wire forms which may be bent on the machine.

Like reference characters refer to like parts in the different views of lthe drawing.

In construction a supporting base 1 is provided'from which, at spaced apart intervals, uprights 2 extend, each having a bearing 3 at its upper end to support a shaft ll, the same extending at each end a distance beyond the bearings. A hand wheel 5 is connected to the shaftl between its ends for turning the same and, if desired, a handle 6 may be used as a substitute for the wheel, the wheel,'l1'owever, being a. preferred construction. Stop pins 7 are mounted on-the uprights 2 and collars 8 are connected to the shaft -l adjacent each end of the uprights, from cach of which an arm 9 eX- tends, the same being adapted to strike against the pins 7 to limit the rotation of the shaft in either direction. The collars 8 may be adjusted to different positions on the shaft being held thereon by set screws so as to vary the rotative movement of the shaft.

At each end of the shaft a member 10 is adjustably secured being held thereon by setscrews` the same being formed into a disk-like head 11 in the face of which a T- shaped slot 12 is cut. The head 11 isof circular outline and in the periphery thereof a plurality of screw-threaded holes 13 are made. The slot l2 is adapted to receive a plurality of different devices such as cylinders 14, pins 15, vor cam-like members 16 as shown in Figs. 2 and 3, which may be loca-ted at various positions in the lengths of the slot-s 12 being held in any position to which they are adjusted in any suitable manner. Also a bar 17 may be connected to a head 11 and extend therefrom as shown, a suitable attaching screw passing through the bar and threading into any opening 13 previously described.

At the corners of the base 1, brackets 18 and 18a are secured on which slotted posts 19 are pivotally mounted. I have shown the pivotal mounting of the posts 19 to brackets 18 at a point below the supporting 'base 1. The pivotal connection of the posts 19 to the brackets 1S is above the base 1. I prefer that the pivotal connection be below the base to give greater rigidity to the construction, but it is to be understood that the structure is operable in either case. Each bracket 18 and 18a has an arc-shaped slot 2O cut therein through which a `bolt 21 mounted on the associated post 19 extends, the same being adapted to receive a nut to bind the I AMIAAI nih* post 19 in any position to which it may be moved with respect to the bracket.

' Various types of members may be adjustably mounted on the posts 19. For instance, I have shown a member 22'connected to certain of the posts, the same having a. connecting stud :22a passing through the slot in the post whereby said member may not only be adjusted lengthwise of the post, but have a. vlimited pivotal movement with respect thereto. A pin and slot. connection illustrated at 23 serves to hold the member in any position to which it may be pivotally adjusted. Arms 24 extend from the member 22 between which a grooved roller 25 is rotatably mounted. The arms 24 extend toward the head 11 but in a plane a slight distance beyond said head and, as shown in Figs. 2 and 3, the member 22 carrying said arms 24 may be inverted if desired in certain instances.

Another member 26 may be mounted on one of the posts 19, being pivotally and adjustably mounted thereon by use 0f attaching screws 26a and the pin and slot connection illustrated at 27. An arm 28 extends from thel member 26 turning upwardly Aat its end and ,being formed with a series of notches 29.

lVith a member 22 as described connected to 011e post 19 at one end of the machine, and a member 26 connected to the ost 19 at the opposite side, and with a cylin er 14 and a pin 15 fixed in the slot 12 of the head 11, as shown in Fig. 2, a plurality of wires 30 may be passed over the roller 25 between the cylinder 14 and pin 15 and over the notched end 29 of the arm 28, it being apparent that the wires lie side by side being received in the notches 29 and in the grooves ofthe roller 25. Then by turning the shaft 4 a partial rotation, these wires may be bent into the form shown at 30a in Fig. 1l. It is obvious that by changing the position of the various members 22, 26, 14, 15and 17, or by substituting a different member, such as 16, for the cylinder 14, or by changing the position of the collars 8 so as to change the amount of rotation of the shaft 4, an almost endless variety of forms may be made with this set up of the machine.

I have also shown a. slotted link member 31 adj ustably connected by a boltv 32 to one of the posts 19, the same carrying at its inner end a sheet metal member 33. With the set up shown in Fig. 3, a plurality of wires 34 may be lbent into the shape illustrated at 34a in Fig. 10. Not only may the wires be passed above the member 33, but the same may be passed through between the members 16 and the pin 15 so as to strike against the member 33, whereupon a different shape or form of wire will be produced. In addition, the pivotal connect-ion ofthe posts v419 to their supporting brackets 18 or 18 permits a wide variety in forms to be made. In fact with this machine the number of wire forms which can'be produced is practically unlimited, and substantially every type of reinforcing wire for sand cores can be made on Va single machine.

From the foregoing, it will be apparent that I have produced a relatively simple but very practical and efficient wire bending machine which may be used to bend many different kinds of wire forms particularly adapted for strengthening and reinforcing sand cores. Of course the machine is not limited to the one' use. Various changes in detail of structure may be resorted to without departing from the invention and I, accordingly, do not wish to be limited to the exact structure shown and described, but consider myself entitled to all modifications of structure which fall within the scope of the appended claims defining the invention.
